Structural Dynamics and Tunability for Colloidal Tin Halide Perovskite Nanostructures

Abstract

2 SnI 4 nanosheets, with R = C 18 H 35 . Under specific synthetic conditions, stable mixtures of 3D nanocrystals CsSnI 3 and 2D nanosheets (Ruddlesden-Popper (R-NH 3 + ) 2 Cs n−1 Sn n I 3n+1 with n > 1) are obtained. These results set a path to exploiting the high potential of Sn halide perovskite nanocrystals for opto-electronic applications.

Tiny spots to light the future: advances in synthesis, properties, and application of perovskite nanocrystals in solar cells

“…Since the first communication on the perovskites applied in solar cells 1 the scientific community has initiated a true revolution in several fields. From the search for new perovskitebased materials [2][3][4][5][6][7] to attempts to understand the formation,…”

“…Since the first communication on the perovskites applied in solar cells 1 the scientific community has initiated a true revolution in several fields. From the search for new perovskite-based materials 2–7 to attempts to understand the formation, self-assembly, and crystallization, 8–10 the mechanisms of charge generation and charge transfer 10,11 perovskites already have their place in the development of optoelectronics. When we take a look at the advance in solar cells, many scientific works have presented numerous ways and possibilities to bring the benefits of perovskites into products for the industrial community through studies with different architectures, 1,12–14 small to large area devices, 13,15–22 and stability tests.…”

Transient Energy-Resolved Photoluminescence Study of Excitons and Free Carriers on FAPbBr3 and FAPbBr3/SnO2 Interfaces

“…In 2009, Kojima et al introduced this class of materials as potential active materials for photovoltaics, reporting a device with efficiencies of around 9%. Based on previous photovoltaic technologies’ progress, people could only predict perovskite photovoltaics’ meteoric upsurge in performance, which exceeds 25% today. − Issues related to stability and the use of lead need to be addressed for their commercial deployment, but progress is being made by introducing polymeric interlayers, − engineering material dimensionality, , and using tin as an alternative to lead. , …”

Stacks of a Hidden Treasure: on the Self-Assemble of Perovskite Nanoplates in Organic Solvents

“…1 This notoriety is due to their outstanding electronic and optical properties such as direct bandgap with high optical absorption near the band edge, 2 high PLQY of their powerful way to investigate these colloidal superlattices is the use of small-angle X-ray scattering (SAXS), and several reports have demonstrated its analytical power and the uniqueness of the insights it provides. 14,21,[27][28][29][30] Thus, we probed the suspensions of PNPls with CsPbBr3 and CsPbI3 compositions in different solvents and conditions using SAXS. We chose a set of different solvents with different viscosities such as hexane, decane, dodecane, and hexadecane.…”
